"To'ell uhoia it concern; l

it known that I, AUGUSTE Canon, a

.citiz'en'ofthe United States,".residing at In- Oreharmin the county of Hampden and of which the following is a speeifi trolleyiine clamps, or devices supportingthe'trolley wire, the object of the -toprovide a simple, cheap, strong and effective device of this'charact'er composed of members adapted to firmly grip and hold the wire between-them in such a manner as to effectively resistthe strains to 'which -clamps of this type are subjected, andv in which improved fastening-means are emiployed fo'r uniting'the sections so that they quickly and conveniently be assembled ma an fdisassembled.

Inthe accompanying drawin'gs,-Figure 1 .isa vertical lo of line clamp em tudinal section of oneform section on li'ne p .'1 of a modified form of line clamp.- Fig. 1s a cross section through the lower clamping member thereof,

showing the form of receiving notch in the shank or stem. Fig. 6 is a longitudinal sec tion showing afmo cation in the construction of the lower clamping member. 7 The devicemay-beconstructed of-any suitable material, and comprises as essential 'ele-- ments a'pair of clamping membersfl and 2.

' said member 2 being formed to: provide a :Thelower clamping member v1 has allongitu dinally curved or convex'upper surface 3, preferably. rovided with a groove 4 for the reception 0 the line wire 5, thelower face of track surface 6 conformmg in general shape I 'to the wire and arranged in a'lmement with the portions thereof at opposite ends of the clamp 'sothat the trolley wheel of acar may '-pass a ong the joint or point. of clamp' of thevvire in a smooth and easy manner.

tendingupwardly'from the center of the convex face of themember 1 is shank orste m '7'- which passes through an sides with longitudinal slots 17 odyi my invention; Fig.

2 'is-a vertical cross sec ti on of, the same. Fig. 3 is a horizontal 3-3 of Fig. 1

, thereon, thus Lt-he' W'IIB.

In the form of the'invention shown in Fig.

a cylindrical thereof'the member2 is ftured' lugs or. cars 19' for connection with th'e 8 in the center of the upper member 2, the ower face of which latter is concaved on an arc concentric with the convex surface of the member 1 and ispreferably provided] with ar'zoincidingt Y oove ,9 for the reception at the wire, whic atter'isbentvbetween the two members in the formof an offset 10, whereby a firm and secure connection be-- tween the clamp and wire is afforded and all tendencyto a, relative longitudinal shifting movement prevented.

The upper end of the shank or stem 7 is adapted to receive I the central eye 11 of a hanger 12 having laterally extending arms provided'at their free ends. with eyes or open: ings 13' for connection with suitable supporting or guy wires, and the u per extremity of the stem is threaded for the reception of a nut 14 which clam s the hanger in position against the-upper at face 15 of the member 2. r The stem or shank is hollowa'nd internally screw threaded to receive a screw. 16 :which enters and closes the same, and said stem is also splitor provided in its 0 posite t ou h which the wire is inserted and removed, the

screw 16 being adaptedto spread the sections of the; shank and thereby force the themember 2, part ll-of thehanger and the nut14, thus firmly locking t e parts in engagement and preventing all liability of casua disconnection from vibrations or strains. When the wire is clamped betweenthe memsameoutwardinto binding engagement with it will be apparent that it will be held and the clamp securely fastened in position preventing any possibility of or shifting of the'clampv upon disconnection 4"the shank or stem 7 is formed'with a receiving slot 17 having an entrance 17 leading thereto from one of the sides of' the shank through which-the wire may be inserted in and withdrawn from said slot in a convenient manner. 7 slottedv for the reception ofa spreading key to hold the same-firmly in binding engagement with theupper clamping member 2 and the nut- 19. this formflof the invention.

the hanger 12 is dispensed with, and in. lieu wires or su orts.

has a solid shank 7 extendprovided with aper-- The shank is also split or '01: wedge 18 and externally threaded for the reception of a nut-1'9, the actionof the wedge serving to spread'the parts of theshank so as too Iment shown in Fig. 6,'the

mg upwardly therefrom and threaded for the reception of a nut holdthe clamping mom-- bers in engagement; This simple form of construction may be employed in cases where a firmer connectionlbetweentheparts is not needed to hold the clamp firmly and securely in position.

Having thus described the invention, what is claimed as new, is

1. A trolley line clamp comprising two separable clamping members having grooved arcuate line engaging faces, one of said members being provided with a central aperture and the other member being provided with a threaded shank engaging said aperture and having'wire receiving slots; and a connecting nut upon the shank.

2. A. trolley lineclamp comprising separable upper and lower clamping members hav ng grooved arcuate line engaging faces,

the 11 per member having a central aperture and t e lower member having an exteriorly and interiorly threaded shank engaging the aperture and provided with wire receiving said shank.

seaeea slots; a connecting nut exteriorly en aging, the" shank and a screw interiorly engaging 3. A trolley line clamp comprising sepa- "rable upper and lower clamping membershaving arcuate line engaging faces, the upper member having a central aperture, and the lower member being rovided Willlllll exteriorly and interior y threaded tubular shank engaging said aperture and provided with wire receiving slots; a hanger having terminal openings and a central eye en aging the shank;'a connecting nut exterior y engaging the threaded shank and a screw in teriorly engaging the latter.

In testimony whereof, I aflix my'signature in presence of two Witnesses.
